Texas Instruments POPA1656IDR
The OPA1656 is a Burr-Brown™ operational amplifier (opamp) designed specifically for audio and industrial applications, where maintaining signal fidelityis crucial. The FET-input architecture achieves a low 2.9-nV/√Hz voltagenoise density and 6-fA/√Hz current noise density, allowing for very lownoise performance in a wide variety of circuits. The high bandwidth and high open-loop-gain designof the OPA1656 delivers a low distortion of 0.000035% (–129 dB) at 20 kHz, and improves audiosignal fidelity across the full audio bandwidth. This device also features excellent output currentdrive capability, offering rail-to-rail output swing to within 250 mV of the power supplies with a2-kΩ load, and can deliver 100 mA of output current.
The OPA1656 operates over a very wide supply range of ±2.25 V to ±18 V or (4.5 V to 36 V)on 3.9 mA of supply current to accommodate the power supply constraints of many types of audioproducts. The temperature range is specified from –40°C to +125°C. The device is offered in an8-pin SOIC package.
